caller: i wish you were on a pbs station for the people who cannot afford satellite. you do great things for education. i would like to ask him as a rural person, who has a highway that barely fits two cars, why should i have to pay for transit when i will never in my lifetime ever going to use it? my mother is 95. she has never been on a train in her life. and why do my tax dollars have to find something like that when it does no good whatsoever for us? and when you give us tax dollars to drive back and forth to work -- and will you give us tax dollars to drop back and forth to work and to the doctor and of that? guest: i would just repeat that this is a national system and there are local interests as well. i'm not saying that the federal government should pay 100% of the chicago transit and rail system. but there is a national interest. you may not use the chicago system, or that the system in phoenix or denver. by you have an interest, as all americans do, in assuring that metropolitan regions have a prosperous economies. i do not know if you're on a state highway
